title: Diagnosis and management of traumatic aorto-right ventricular fistulas.
abstract: BACKGROUND
  Traumatic aorto-right ventricular (Ao-RV) fistulas are rare lesions that result in congestive heart failure if left untreated. Early diagnosis and prompt surgical intervention are required to avoid the natural outcome of cardiac decompensation.
  
  
  METHODS
  All cases of traumatic Ao-RV fistula described in the English literature since 1958 were reviewed. The clinical presentation, methods of diagnosis, and treatment strategies were assessed to determine the pathophysiology, natural history, and outcome of surgical intervention.
  
  
  RESULTS
  Forty cases of traumatic Ao-RV fistulas were described in the English literature. There were 39 men and 1 woman, with a mean age of 28.3 years (range, 15 to 50 years). Twenty-two (55%) patients had isolated Ao-RV fistulas. Fourteen (35%) had Ao-RV fistulas with aortic insufficiency. Definitive surgical repair was performed in 38 patients. The associated aortic valve injuries were managed with repair techniques or replacement with prosthetic devices. The surgical outcomes in all patients were satisfactory.
  
  
  CONCLUSIONS
  The pathophysiology and natural history of Ao-RV fistulas involves the development of congestive heart failure. Traumatic aortic insufficiency frequently is associated with this disorder. Early diagnosis and prompt treatment are necessary to avoid the natural outcome of cardiac decompensation. Definitive repair should be performed with the aid of cardiopulmonary bypass during the same hospitalization.
